I didn’t realize until Ukraine 2022 that true tanks are infantry weapons. They are low profile (same height as a soldier) and there to deliver artillery style impact but at point blank range, side by side with riflemen. Why do tanks need infantry? You can immobilise a tank with a petrol bomb. Something with the firepower of a tank also needs FIBUA close quarter combat to defend it. It is a bizarre quandary.
